New cartridge vs. Re-tipped

+1 Andy Kim. He upgraded my DL 103. Highly recommended.

Like @dwette said.  And try and do some research on your specific case. Who did the re-tip? If you can find out, read reviews of their work.

I had a Denon DL103 with a missing cantilever. I sent it off to an independent re-tipper who had great feedback.  The upgraded cart I got back was transformed to another level. There are good re-tippers out there.
